How do I make my router forget my pc?

[BlackstarReach]

Hey guys, I accidentally locked my pc out of my router settings (Don't ask, I'm just really dumb.) And I need to find a way to manually change my pc's IP address or something in order to make it appear as a completely new connection. How do I do this exactly? Thanks
